Information you should know before
operating the unit
What is blood pressure?
A force is created by the heart as the ventricleforcibly
ejects blood into the blood vessels and through the
vascular system. Another force is created by the arteries as they resist the blood flow. Blood pressure is the
result of these two forces.
What are systolic and diastolic pressures?
Systolic pressure is the highest pressure at the height
of the heart`s contraction. Diastolic pressure is the lowest pressure when the heart is resting.
Is my blood pressure normal?
See the blood pressure classification chart released
by the WHO (World Health Organization) on page 35
for evaluation of your blood pressure level.
What about low blood pressure?
In general, a lower blood pressure reading is better unless it causes unpleasant symptoms such as fainting
and/or lightheadedness.
Fluctuation and variation in blood pressure
The following chart shows possible blood pressure
fluctuations during a 24-hour period.

About the Unit
Function description
Based on oscillometric method and silicon integrate
pressure sensor technology, blood pressure and heart
rate can be measured automatically and non-invasively which helps to ease the operation. The Geratherm
med control have 2 x 99 memories with date and time
display, a big LCD screen and arrhythmia detection.
The RCC (radio controlled clock) function can automatically receive the German radio clock signal (DCF77)
to adjust the clock accurately. And the colour LED for
indicates the class according to WHO of your blood
pressure. Also the monitor has the function of averaging the latest three records.

e. Then the monitor begins to pressurize
automatically.
During the measurement, the current pressure will
display on the LCD, and the bars will automatically
rise up or fall down with the current pressure in the
cuff. The heart sign will glimmer with the heartbeat
during the pressure are falling down.
f. After measurement, the result of systolic, diastolic
and pulse rate will all display on LCD. And irregular
heartbeat symbol and blood pressure classification
indicator will twinkle (picture 3). The result will be
automatically memorized by itself. And the COLOUR CHANGE LED will also indicate the blood
